What are the four lobes
frontal
parietal
temporal
occipital
Who's Phineas Gage?
Dynamite + iron rod = frontal lobe destruction
Where is the motor cortex located
Frontal lobe
where is the sensory cortex located
Parietal lobe
Where is the visual cortex located
occipital lobe
where is the auditory cortex located
temporal lobe
The peripheral nervous system is made up of what
sympathetic
parasympathetic
Sympathetic part of the peripheral nervous system is also known as
fight and flight
Parasympathetic part of the peripheral nervous system is also known as
rest and digest
3 pieces of selective attention
Inattentional blindness
Change blindness
Hemineglect
our awareness of ourselves and our environment
consciousness
Spontaneous states of consciousness
Daydreaming
Drowsiness
Dreaming
Physiologically induced states of consciousness
hallucinations
orgasm
food or oxygen starvation
Psychologically induced states of consciousness
sensory deprivation
hypnosis
meditation
the interdisciplinary study of the brain activity linked with our mental processes
cognitive neuroscience
the principle that info is often simultaneiously processed on separate conscious and unconscious tracks
dual processing
a condition in which a perosn can respond to a visual stimulus without consciously experiencing it
blindsight
failing to see visible objects when our attention is directed elsewhere
inattentional blindness
failing to notice changes in the environment
change blindness
the focusing of conscious awareness on a particular stimulus
selective attention
the biological clock
circadian rythm
what is the recurring sleep stage during which vivid dreams commonly occur
REM sleep
the relatively slow brain waves of a relaxed, awake stae
alpha waves
periodic, natural, reversible loss of consciousness
sleep
false sensory experiences, such as seeing something in the absence of an external visual stimulus
hallucinations
the large, slow brain waves associated w deep sleep
delta waves
light striking the retina signals the suprachiasmatic nucleus to suppress the pineal gland's production of the sleep hormone melatonin.
the biological clock
A sleep disorder having recurring problems in falling or staying asleep
insomnia
a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly in to REM sleep, often in inopportune times.
narcolepsy
a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
sleep apnea
a nerve cell; basic building block of the nervous system
neuron
a neuron's bushy, branching extensions that receive messages and conduct impulses toward the cell body
dendrites
the neuron extension that passes messages through its branches to other neurons or to muscles or glands
axon
a fatty tissue layer segmentally encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one node to the next
myelin sheath
a neural impulse; a brief electrical charge that travels down an axon
action potential
the level of stimulation required to trigger a neural impule
threshold
a junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
synapse
tiny gap at the synapse junction is call
synaptic gap
synaptic cleft
chemical messengers that cross the synaptic gaps between neurons
neurotransmitters
a neurotransmitter's reabsorption by the sending neuron
reuptake
